Mitral peak early diastolic filling velocity to deceleration time ratio as a predictor of prognosis in patients with chronic heart failure and preserved or reduced ejection fraction

摘要

ObjectiveDoppler derived mitral peak early diastolic filling velocity to deceleration time ratio (E/DT) has been proposed as parameter for predicting prognosis in general population. This study prospectively investigates the incremental prognostic value of E/DT over clinical, conventional echocardiographic and mitral-Doppler variables in patients hospitalized for decompensated heart failure (HF).
